In Kharif 2022 and Kharif 2023, a research was conducted in the fields of farmers in Dera Ghazi Khan to assess the impact of different zinc levels on the quantity and quality of cotton produced. Three replications of the experiment were carried out using a Randomised Complete Block Design. There were five different zinc application levels: 0, 5, 10, 15, and 20 kg ha^-1. The lowest average seed cotton yield was seen in the control group in 2022 and 2023, at 2462 kg/ha and 2371 kg/ha, respectively. However, in 2022 and 2023, the 20 kg ha^-1 zinc treatment showed the greatest yield of 2683 kg/ha and 2511 kg/ha, respectively, indicating an increase in yield of 5.90 % and 8.98 % over the control. T₅ (20 kg ha^-1) showed the highest number of productive bolls per plant, whereas T₁ (control) showed the lowest number. In contrast, the control group showed the highest plant height when compared to the other treatments. T₅ (20 kg ha^-1) had the largest number of sympodial branches per plant and the lowest number of monopodial branches per plant compared to the control. The data clearly shows that the administration of various zinc dosages had a substantial impact on the number of bolls per plant, plant height, number of sympodial branches per plant, number of monopodial branches per plant, and seed cotton production. Zinc must thus be applied to cotton in order to improve its production and quality.
